7 years ago ( back when this was unheard of ) I searched and searched for this solution. During the development I saw a few emerge. Some fell out and others made a successful product. For the D.I.Y types there are lot of ways to achieve the goal I have made, including my project in itself (DIY kits). It can be done for very cheep and I will always cater to that crowd. Though I decided to invest some time and money in making this 4-play thing. The 4-Play is a modular controller adapter for both the modern and retro gamers connecting all your favorite console controllers (up to four at once) to your computer. The aim here is for the consumer. It require very little hassle and you just plug and play.
This is not for the world of do it yourself'er. There simply are some better suited projects out there for that. Undeniably most of us ow our inventions to v-usb and Raphael. They made this all happen!
So yeah, if this is not your thing I get that, also I figure the best place to talk about this was in the retail section as this project is now being kick started. If that was a bad choice move it to where its best fitted. The kickstarter is a tad bit high with all the tooling that has gone in to it and we decided to pay that up front. If that profit can not be cleaned up by this KS, there are alternatives.
